There’s solely a sliver of the moon on show tonight, however there’s nonetheless an opportunity to see some cool geological options on its floor, if we glance onerous sufficient.
The moon is trying slightly darker proper now attributable to the place we’re within the lunar cycle, a sequence of eight distinctive phases of the moon’s visibility. The entire cycle takes about 29.5 days, in line with NASA, and these totally different phases occur because the Solar lights up totally different elements of the moon while it orbits Earth.
So let’s examine what’s taking place with the moon tonight, Aug. 18.
What’s at the moment’s moon part?
As of Monday, Aug. 18, the moon part is Waning Crescent, and it’s 25% lit as much as us on Earth, in line with NASA’s Each day Moon Commentary.
We’re on day 25 of the lunar cycle, so it is actually near the New Moon. There’s not a lot moon on show, however there are some things we will nonetheless look out for. With no visible aids aside from your eyes, attempt to spot the Oceanus Procellarum and the Kepler Crater. These are positioned within the prime left of the moon (backside proper, for those who’re within the Southern Hemisphere).
With binoculars, see much more, together with the Grimaldi Basin and the Mare Humorum, and with a telescope, take pleasure in a glimpse of the Reiner Gamma and the Schiller Crater, too.
When is the following full moon?
The following full moon will probably be on Sept. 7. The final full moon was on Aug. 9.

What are moon phases?
In line with NASA, moon phases are brought on by the 29.5-day cycle of the moon’s orbit, which modifications the angles between the Solar, Moon, and Earth. Moon phases are how the moon seems to be from Earth because it goes round us. We at all times see the identical aspect of the moon, however how a lot of it’s lit up by the Solar modifications relying on the place it’s in its orbit. That is how we get full moons, half moons, and moons that seem fully invisible. There are eight important moon phases, they usually comply with a repeating cycle:
New Moon – The moon is between Earth and the solar, so the aspect we see is darkish (in different phrases, it is invisible to the attention).
Waxing Crescent – A small sliver of sunshine seems on the precise aspect (Northern Hemisphere).
First Quarter – Half of the moon is lit on the precise aspect. It seems to be like a half-moon.
Waxing Gibbous – Greater than half is lit up, however it’s not fairly full but.
Full Moon – The entire face of the moon is illuminated and absolutely seen.
Waning Gibbous – The moon begins shedding gentle on the precise aspect.
Final Quarter (or Third Quarter) – One other half-moon, however now the left aspect is lit.
Waning Crescent – A skinny sliver of sunshine stays on the left aspect earlier than going darkish once more.
